© 2018 Hydrogen generation from water using solar energy has grown into a promising approach for sustainable energy production. Over the last years, graphitic carbon nitrides (g-C3N4, CN), polymers based on the heptazine-group, have been widely applied as photocatalysts for H2evolution. The poor charge separation efficiency of CN is considered the major drawback. Here, we investigated the effect of coupling CN with different types of carbon nanotubes on the charge transfer properties and the photocatalytic H2evolution. We used carbon nanotubes (CNTs) of different wall number (single (SWCNTs), double (DWCNTs) and multi-walled (MWCNTs) CNTs) for the development of full-organic CN based composite photocatalysts. Photoactivity was drastically affected by the content but more importantly by the nature of the CNTs. The SWCNTs functionalized CN composites were the most active presenting approximately 2–5 times higher H2evolution than the corresponding DWCNTs and MWCNTs functionalized CN under both solar and pure visible light irradiation. Photoactivity was primarily controlled by the improved electronic properties linked with the abundance and stability of photogenerated charges as evidenced by electron paramagnetic resonance spectroscopy. Transient absorption spectroscopy verified the transfer of reactive electrons from CN to CNTs. CNTs functioned as electron acceptors improving charge separation. The data suggest that charge transfer is inversely proportional to the wall number of the CNTs and that photoactivity is directly controlled by the size at the nanoscale of the CNTs used. In the CNTs/CN nanocomposites, photogenerated electrons are transferred more efficiently from CN when SWCNTs are used, providing more available electrons for H2production.

Evans A, Luebke R, Petit C, 2018, The use of metal-organic frameworks for CO purification, Journal of Materials Chemistry A, Vol: 6, Pages: 10570-10594, ISSN: 2050-7488

© 2018 The Royal Society of Chemistry. Carbon monoxide (CO) represents a key feedstock in the petrochemical industry and must be produced in sufficient purity for industrial use. Such requirement imposes strict performance targets on separation technologies and processes employed to purify CO. An important consideration, adding further difficulty to this separation, is the chemical complexity of some CO-containing streams which include gas molecules such as H2, CO2, N2, H2O. While processes such as cryogenic distillation and/or absorption can be applied, the associated high-energy consumption and/or poor stability of the absorption solvents remain key barriers and considerations in large-scale deployment. In this review, we provide an up-to-date account of the literature on adsorption technologies for CO purification with particular emphasis on the use of metal-organic frameworks (MOFs). We highlight key chemical and structural features of MOFs which govern the adsorption mechanisms as well as the resulting performance metrics (e.g. uptake and selectivity). We discuss important aspects of technology scale-up including sorbent robustness, manufacturability and performance under 'real' conditions. A comparison of literature reported adsorbents, tested for CO adsorption, including a benchmark material is provided. Based on our analysis of the field, we present an outlook of future challenges as well as opportunities for future research in this area.

© 2018 Elsevier Ltd Two different nanoclay minerals were combined with nanophase anatase TiO2for the synthesis of clay-based nanocomposites for improved photocatalytic properties. A new Halloysite (Hal) + Sepiolite (S) - TiO2ternary nanocomposite was prepared using halloysite from Utah, USA and a recently discovered sepiolite from Greece. Three nanocomposites were synthesized with Hal-TiO2, S-TiO2and [Hal+S] to TiO2. As a result, TiO2particles (anatase) were homogeneously deposited and dispersed on the clay surfaces. Phase composition, particle morphology and physical properties of these nanocomposites were characterized by XRD, ATR-FTIR, FE-SEM, DRS-UV–Vis and N2-sorption/desorption isotherms at 77 K. The photocatalytic activity of the clay mineral-TiO2nanocomposites was examined in the decomposition of paracetamol and tetracycline antibiotics as well as dye Rhodamine-B. The nanocomposites exhibited higher photocatalytic activity under UV irradiation for the decomposition of the targeted pollutants than the benchmark in the field, i.e. TiO2- P25 photocatalyst.

Petit C, 2018, Present and future of MOF research in the field of adsorption and molecular separation, Current Opinion in Chemical Engineering, Vol: 20, Pages: 132-142

© 2018 Elsevier Ltd It is a critical and exciting time for research on adsorption using metal–organic frameworks (MOFs) as we witness the commercial release of the MOF-based products TruPick and ION-X, two MOF-based products with application in the food packaging and electronic gas delivery platform sectors, respectively. Such milestones call for reflection on the outputs of MOF research in the field of adsorption so far and the challenges and opportunities lying ahead. To this end, this review provides a snapshot of current trends in this research space (i.e. new adsorption application, manufacturing, role of modeling), highlights the most promising structures for given applications (i.e. in gas adsorption, gas storage, molecular separation, water purification and harvesting), points to technical barriers, and exposes a vision for future research in this area.

Stafford J, Patapas A, Uzo N, Matar OK, Petit Cet al., 2018, Towards scale-up of graphene production via nonoxidizing liquid exfoliation methods, AIChE Journal, ISSN: 0001-1541

© 2018 American Institute of Chemical Engineers. Graphene, the two-dimensional form of carbon, has received a great deal of attention across academia and industry due to its extraordinary electrical, mechanical, thermal, chemical, and optical properties. In view of the potential impact of graphene on numerous and diverse applications in electronics, novel materials, energy, transport, and healthcare, large-scale graphene production is a challenge that must be addressed. In the past decade, top-down production has demonstrated high potential for scale-up. This review features the recent progress made in top-down production methods that have been proposed for the manufacturing of graphene-based products. Fabrication methods such as liquid-phase mechanical, chemical and electrochemical exfoliation of graphite are outlined, with a particular focus on nonoxidizing routes for graphene production. Analysis of exfoliation mechanisms, solvent considerations, key advantages and issues, and important production characteristics including production rate and yield, where applicable, are outlined. Future challenges and opportunities in graphene production are also highlighted.
